25 Claims.

The present invention relates to agricultural implements and is moreparticularly concerned with that type of implement known asside deliveryrakes. The primary object of our invention is to provide a new andimproved rake embodying certain novel features which contribute toproduce a rugged, highly eflicient implement that is extremely flexibleto meet a wide variety of operating conditions.

A more specific object of our invention is to provide a novel arranement of the main frame, rake reel, and supporting wheels wherein thereel is enabled to rake the ground directly behind both of the frontwheels; This is particularly advantageous when raking hay underconditions common to the check and border system of irrigation, which iswidely used in certain semi-arid regions, as it allows the hay to beraked from the top of the border without damage to border or rake byrunning with the wheel on top of the border, and also permits working upclose to the border by running with the wheel closely alongside theborder.

A further object is to provide an improved frame construction which isstrongly braced to withstand the severe twisting stresses to which sidedelivery rakes are frequently subjected and which, at the same time,provides ample clearance for handling the heaviest crop.

Another object is to provide an improved dual caster wheel suspensionfor the rear end of the rake wherein one of the wheels is adjustablevertically to raise or lower the frame with respect to the ground, whilethe other wheel is spring-controlled and is free to follow the surfaceof the ground, bearing its share of the load as field surfaceirregularities demand.

Still another object of the present invention is to provide an improvedspring suspension and driving connection'for the rak reel.

Another object is the'provision, in a tractor mounted side delivery rakehaving a driven sprocket and a releasable clutch, of means for removingthe reel driving chain bodily from the driven sprock'et over the clutchto permit unhitching the rake from the tractor without disconnecting thechain. A related object is to provide means on the tractor forsupporting the chain when the rake is unhitched. v

A further object of our invention is the provision-of a new and improveddraft connection by means of which the rake can be quickly and easilycoupled to or uncoupled from the tractor, and one of th features of thisdraft connection is a Jack stan which can be swung up to a raisedtransport position on the rake frame. These and other objects andadvantages of the present invention will become apparent to thoseskilled in the art after consideration of the following detaileddescription of the embodiments thereof illustrated in the accompanyingdrawings.

Referring now to the drawings, and more particularly to Figures 1, 2 and3, the side delivery rake comprises a generally fore and aft extend ingmain frame It supported at its front end on a pair of laterally spacedground wheels II and I2, and at its rear end on a pair of obliquelyarranged caster wheels i3 and it which are disposed substantially inline with their respective front wheels ll, I2; Mounted on the mainframe l0 oblique to the line of forward travel is a reel supportingframe 15, on which is journaled the rake reel IS. A draft frame 20 atthe front end of the main frame Ill affords mean for hitching the raketo a draft vehicle or team, as the case may be.

' jects laterally "beyond plan. and comprises a pair of laterallyspaced, longitudinally extending members 2| and 22 of unequal lengthwhich are connected together at their front ends by a transverselydisposed U- shaped member 23 having rearwardly extending arms 23' and23". Each of the members 2|, 22 is arched upwardly, as best shown inFigure 2, to provide clearance for the rake reelg|6 which is disposedbeneath the main frame and prothe members 2|, 22. A caster wheel supportbracket 24 is fixed to the rear end of each of the members 2|, 22, and

slidably disposed within the bracket for vertical movement is a standard25, the lower end of which is forkedto receive the caster wheel.

The draft frame 26 comprises a pair of laterally spaced, forwardlyconverging members 28 and 21 which are pivotaliy connected at their rearends by transversely aligned pivot bolts 30 to brackets 3| fixed to thefront edge of the transverse frame member 23. The'draft frame members26, 21 are connected together intermediate of their ends by atransversely disposed vertical frame structure 32 which serves also as asupport for certain control members which will 'be described in detailpresently. Suitable hitch means (not shown) is provided at the front endof the draft frame 20 for connecting the rake to the drawbar of atractor.

The reel supporting frame i is generally rectangular in plan andconsists of front and back members 33, 34 disposed beneath thelongitudinal frame members 2|, 22, diagonal to the line of forwardtravel. The outer ends of the members 33, 34 are connected by a crossmember 35. while the inner ends are connected together by meansincluding a bar 36 and 'reel supporting member 45. A plurality ofU-shaped strippers 40 are fixed to and extend between the members 33, 34at regularly spaced intervals to strip the cut vegetation from the teethon the raking reel l6 as the latter rotates. A frame extension member 4|is disposed parallel to and spaced rearwardly from the back member 34and is fixed at its ends to the rear ends of the main frame members 2|and 22. The reel frame member 34 and extension member 4| are connectedtogether by brackets 42 and 43. A transversely disposed arched bracingmember '44 is fixed to the outside of the right frame member Hand to thereel frame "near the outer corner thereof.

The right end member 36 of the reel supporting frame |5 has a rearwardlyextending arm 31 which overlies the front end of the reel frame member34 and is bolted thereto at 38. The member '36 is arched upwardly at 50and terminates in a downwardly extending portion 5| to which the rearend of the reel supporting member 45 is welded at 49. A short length ofangle iron 52 is welded to the lower end of the downwardly extendingportion 5| and to the horizontal portion of the member 36 at 48, forminga loop through which the right end of the rake reel shaft extends. Thereel supporting member 45 extends forwardly and laterally inwardly fromits point of connection with the member 5| and is bolted at 41 to 23between the wheels l2. The inner or front end of the reel frame member33 overlies the reel supporting member 45 and is secured thereto by abolt 46, as best shown in Figure 3. Additional support for theright-hand end of the reel frame I5 is provided by the right-hand arm23" which is.extended-rearwardly and is connected to member 45 by bolts24'.

the transverse frame member a compression spring 63.

carried by the forward reel head 53, which serve to maintain the raketeeth 58 at the proper angle with respect to the ground as the reelrotates. The reel shaft 56 is journaled at its rear end in a bearingblock 60 which is slidable vertically between guides 6| end member 35.The bearing block is connected to the lower end of a vertical rod 62which extends upwardly through a suitable hole in the member 35 and issupported at its upper end on The forward end of the reel shaft 58 islikewise journaled in a yieldingly supported bearing which will bedescribed in detail presently. v

Power for driving the reel 6 is derived from the ground wheels II, l2which are mounted on a-transverse axle 64 outside of the frame members2|, 22 and are connected with the axle to drive the same, the axle 64being journaled in any suitable bearings fixed to the main frame In. Anenclosed gear housing 65 is mounted on the main frame It at the Junctionof the longitudinal frame member 22 and the transverse member 23 and isalso fixed to a diagonal bracing member 66 extending between members,23". The axle 64 extends through and is Journaled in the housing 65, andfixed to the axle to the reel shaft 56 in line with the sprocket 14,

and trained over the sprockets is a driving chain 16. The outer endnaled in a bearing 86 fixed to one end of a radius arm 8|, the other endof the arm having a bearing portion 82 which is journaled on thecountershaft 12 between the sprocket 14 and gear housing 65.

on the outer end of embraces the rod 83 above the arch 50. A nut 36 isthreaded on the upper end of the rod 83, and between the nut and thetrunnion block 85 is a compression spring 9| which cushions the weightof the reel on the arm 86. The lifting arm 86 is pivoted at 92 on atriangularly shaped bracket 93 mounted on the top of the reel supportingmember 45, and fixed to the arm 86 between the pivot 92 and the trunnionblock 85 is an upwardly extending arm 94, the arms 86 and 94 forming abell crank which is operative to raise 'or lower the drive end of therake reel l6. A trunnion block 95 is pivoted on the end of the arm 94,and threaded into the trunnion block is a forwardly extending rod 96,the front end of which is journaled in a plate I08 welded to a an outeror rearward head 54 fixed to the underside of the of the reel shaft 56is jour-' 'wardmost caster V point ground contact which enables the raketo vertical post IOI fixed to and extending between members 22 and 22".A universal joint yoke I02 is fixed to the front end of the rod 96 andhas a shoulder I02 that bears against the plate I in the manner of anend vthrust bearing. A second yoke I04 fixed to the rear end of a shaftI06 is operatively connected with the yoke I02 to complete the universaljoint, and the shaft I06 extends forwardly therefrom to a point withinreach of the operator at his station on the tractor. The front end ofthe shaft I06 is slidably journaled in a bearing I06 pivoted on thevertical frame 22, and has a crank handle III by means of which theoperator turns the shaft. From the above, it is seen that the inner orforward end of the rake reel is raised or lowered relative to the mainframe for the purpose of leveling the reel with respect to the ground,by turning the crank H0.

The rear end of the main frame I0 is raised or lowered relative to therear caster wheel I2 for adjusting the rake to the proper height abovethe ground, and this is accomplished through the agency of an adjustingdevice III mounted on the long frame member 2I near the front endthereof. The adjusting device III comprises a nut H2 and screw member II2 in threaded engagement therewith, the nut being held against.rotation by a suitable bracket member II4 on the frame member 2|, whilethe screw member is joumaled in a bearing bracket H6 and is operativelyconnected by a universal joint II6 to a hand crank- I20 disposed withinreach of the operator. The shaft I2I of the crank I22 is journaledwithina bearing sleeve I22 through which it is also slidablelongitudinally, and the bearing I22 is pivoted on the vertical frame 22.The nut I I2 is connected with the vertical standard 26' of the casterwheel I2 through an arrangement of links and chains, indicated generaliyby the reference numeral I22, which is trained over pulleys I24 and I26to a cap I24 fixed to the top oftthe vertically slidable standard".Thus, when the crank I22 is turned in one direction, the standard 26 ispulled downwardly with respectvto the main frame I0, thereby raising therear end of the frame with respect to the ground.

Normally, the rake is supported by the two main wheels II,. I2 and theleft-hand, or rearwheel I2, providing a three conform readily to unevensurfaces. The righthand caster wheel I4 is independently movablevertically and is spring-controlled by means which will now bedescribed, permitting it to 7 follow the surface of the ground and-bearits share of the load only as field surface irregularities demand. Alever I20 is pivoted at III on the frame member 22 and has a tensionspring I22 attached to its lower end, the other end of the spring beingfastened to achain I 02 which is trained under a pulley I24 and isattached to a cap I26 fixed to the upper end of the vertically slidablestandard 26 of the caster wheel I4. The lever I20-is adjustable toincrease or decrease the tension ofrthe spring I22 and is held inadjusted position'by means of detent controlled'by a latch I26andengaging a notched sector I31. The front caster wheel I4 thus acts as anadjustable spring-controlled gauge wheel, following the ir regularitiesof the ground surface and helping to boost the rake over mounds orhills.

Another embodiment of our invention is illustrated in Figures 4 to-11,inc1usive, which and is attached top surfaceeiil.

welded at I (see 3 show a tractor-carried or integral rake constructedin accordance with the principles of the invention. Structure of thisrake which is similar to that previously described is given the samereference numeral with the suffix a.

The tractor mounted thereon are journaled in the final gear housings MI.The frame of the tractor consists of apair of laterally spaced,

I60 adapted to fit on top of the tube, and a flat platform members I46is secured to its respective tubular member by a pair of fore and aftspaced bolts I62 extending through vertically aligned holes in theplatform and tubular members. The heads I62 of the bolts aresubstantially cone-shaped and project upwardly from the top surface I6Iof the platform member to facilitate the hitching operation, as will bedisclosed in more detail presently.

In Figure 12, which shows a modified form of the coupling device, thecasting I46 has inte- 'grally formed, tapered aligning lugs I41projecting upwardly from,

tapped to receive the threaded ends I42 of bolts I62, the heads of thebolts bearing against the bottom of the tubes I44, I46. The lugsl" servethe same capacity as the cone-shaped bolt heads I62 shown in Figure 8.

The main frame Ilia 0f. the rake comprises two laterally spaced fore andaft extending arched members 2Ia and. 22::

I64 fixed to-the arched members by means of laterally beyond its pointof connection frame member 22a and is bolted at I66 to the front end ofthe reel frame downwardly curved end portion I61 which is Figure 11) tothe end of member 26a. A diagonal brace I69 is fixed to and extendsbetween the extension 200 and member V 26a to provide additionalrigidity for the connection therebetween. The'front ends of the members2Ia, 22a are pivotaliy connected for verti-- cal swinging at 166 to thearms I 61 of a transversely arranged U shaped draft member I 60, thebight portion 01' which is in the form of a horizontally disposed plateI6I having two pairs of fore and aft spaced holes I62, I63 providedtherein. The holes I62, I62 are arranged so as to engage the bolt headsI63 when the draft member I60 is mounted on the tractor, and the plateI6I rests on the flat top surface I6I of the platform members I46. Theplate I6I .is secured to the platform members I46 by eans of two U-boltI64 each disposed between'the holes I62, I62 and extending under thetubular members I44, I46, respectively, and upwardly through laterallyspaced holes I66 in the plate. One end I66 of the U-bclt is threaded andhas a nut I10 which the top surface I6I' thereof.- Holes I42 are drilledin the castings I46 and Th cross member I64 projects with the member22a. The member I64 continues diagonallyrearwardly from v r the bolt I66to form an extension 200 having a bears against the top of the plate I8lto draw thefrom the leading edge of the plate to bear against.

the top of the tubular member, providing an ad'- ditional point ofcontact for greater fore and aft stability.

' Swingably mounted on the front end. of the rake is a jack stand I12which supports the frame when the latter is disconnected fromthetractor. The jack stand I12. is preferably U-shaped and the ends of thearms I14 thereofare disposed between U-shaped brackets I15 fixed to theframe members 2Ia, 22a, respectively. Each of the arms I14 has alengthwise-extending slot I18 provided in its end, andthe extremity ofthe arm is rounded at I80 about the outer end of the slot I18 as acenter. bracket I15 and extends the stand I12 being swingable about thepin Bias a pivot and also slidable relative thereto along the length ofthe slots. The-bracket I15" also functions as a limit stop, the arm onthe jack stand I12 and the weight of. the frame causes the pins IN todrop to the inner ends of the slots I18, as shown in Figure 6, the stopI15 prevents the stand from folding up. The stand I12 is swung up totransport position by moving the same so that the pins I8I occupypositions in the outer ends of the slots I16, whereupon the round endsI80. of the legs will clear the limit stops I15 and be raised to theposition illustrated in. A hook I82, which is fastened at I83 to theplate I8I, engages an apertured lug I84'provided o'na cross bar I85fixed to and extending between.

the arms I14, to holdthe stand in raised trans--.

extends through aligned apertures in the bight I12 and cross bar I85 andis in threaded engage-'- ment with the barrel portion I80. Friction ofthe base I93 on the ground prevents the shaft I82 from turning with thebarrel portion I80 and thus causes the shaft to be extended or retractedas the operator turns the barrel portion, using the spokes I! ashandles. When the rake is to be unhitched from the tractonthe powerdriving connection, which will be described presently, is firstdisconnected, the hook I82 is then disengaged from the lug I84, thestand I12 is swungv down to lowered position, and the Jack shafts I82are turned out by hand until their bases I83 rest on the ground.

AsLin-the previously described embodiment, the

raking reel ISa is yieldingly supported on the reel, '1 frame I5a,.andprovision is madefor adjustingthe forward or inner end of the rakevertically with respect to the ground. The bearing end aof the radiusarm' 8Ia-.is supported. on a rod" 83a and spring 8Ia, and the latterbears against a.

trunnion-block 85a pivoted between. the outer gageablewithnotches 203in. the'top edge of the support I86;

Power-for driving the rake reel IGa'. is derived from the. rear axle ofthe tractorv and is transmitted by means including aidrive'v sprocket.204

which is bolted at 205- to the inner face of theright-hand drive. wheel3.. A driven sprocket 206 is journaled on an intermediate drive or powershaft 2I0 inline with the sprocket 204 and is operatively connectedtherewith through the agency of a. clutch 208 which will be described inmore detail presently. A drive chain 2 is trained over the sprockets 204and-208 and is held tightly against the same by means of a chaintightener sprocket 201 iournaled on. an arm. 208 whichis pivoted at 2I1on. the-frame member 2211 andis yieldingly held against the chain byaspring 2l8 which is anchored to a bracket 2 I 8;provided.on agearhousing 2I2. The power shaft 2I0' is disposed'adjacent the front endof the main frame I01; and transverse to the line of forward travel,

and the outer end of the shaft extends through and is journaled in thegear housing 2I2' which is fixed tothe extension 200 of crossmember I54by means of a bracket M8 and to the end of the reel frame member 3811 bymeans of'a bolt 2 and spacer 2| 5. A diagonally disposed countershaft2.I6.is journaled in the gear housing 2I2 and tween. A sprocket 14ais'fixed to the end of thecountershaft 2.I6 in line with the sprocket15a'on the reel shaft 56a and is connected therewith through the agencyof a drive chain 16a. The inner or'forward end of the radius rod 8Ia isjour-- naled for vertical swinging on the countershaft 2I6. betweenthesprocket 14a and the gear housing 2I2.

The clutch 208 provides means for interrupting: the transmission ofpower to the reel ltd when-the-rake is being transported, and comprisesa driving member 222 fixed to the side of,.the sprocket 206- oppositethe gear housing and a spring biased driven member 223 movable axiallyalongthe shaft 2I0 into and'out of engagement with the driving member.member 223 is slidably keyed to the shaft 2I0 in driving connectiontherewith and is yieldingly' held in engagement with the driving-member222' bymeans of a spring 224" which abuts against a cap 225 pinned tothe end of the shaft 2I0. The

clutch is disengaged or released through the.

agency of a shifting fork 228 journaied for vertical swinging betweenraised. and lowered positrons on one end of a transversely disposedshaft =230-whichis slidablysupported on two brackets The driven clutch23l, 232 fixed to the under side of the cross bar I54. The shifting fork226 has a U-shaped portion 233 adapted to lie within an annular groove234 provided in the driven member 223 and is swingable out of engagementtherewith to the raised position shown in Figure 10. Th shifting fork isheld on the shaft 230 by a split cotter pin 235, and the shaft is madeto move axially, carrying the shifting fork and clutch member with it,by means of a lever 236 pivoted at 240 to the shaft outside of thebracket member 232. The lever 236 has a rearwardly projecting extension2 (see Figure 4) which bears against the bracket 232 when the lever isswung and earns the shaft 236 in the direction for disengaging theclutch.

The shifting fork 226 is provided at its outer end with a finger grip242-by which the fork can be swung from engaged or lowered position toraised or inoperative position, and is held in either position by meansof an over-center spring connection comprising a curved link 243 andspring 244, The link is pivotally connected with the shifting fork at245 and is fastened at the other end to the spring 244 which is anchoredat 246 to the end stripper 46a. When the shifting fork is engaged in thegroove 234 of the driven clutch member, as in Figure 9, the line of pullbetween the points 245, 246 passes below the axis of the shaft 230, andthe shifting fork is held down in the groove. When the fork is raised tothe position shown in Figure 10, however, the line of pull passes abovethe axis of the shaft 230, by virtue of the curved link 243, and thefork is now held in raised position, allowing the operator to use bothhands while removing the drive chain 2 endwise over the clutch 269.

When the rake is to be unhitched from the tractor, the driving chain 2|l is removed from the sprocket 206 and withdrawn over the end of theclutch 209, with the shifting fork 226 raised to the position shown inFigure 10 to provide clearance. The chain is then looped over the finalreduction housing I of the tractor and supported on bracket hooks 250and 251 (see Figure 6) fixed to the housing, said hooks being passedthrough the links of the chain to hold the same securely in place, asshown in Figure 7. In this way it is unnecessary to disconnect the linksof the chain when the rake is temporarily unhitched from the tractor.

The rear end of the main frame Illa. is raised or lowered relative tothe rear caster wheel l3a through the agency of an adjusting device 252mounted on the longitudinal frame member 2la near the front end thereof.The adjusting device 252 comprises a worm 253 fixed to a fore and aftextending shaft 254 which is journaled on a bracket 255 and has a handle256 at the front end thereof disposed within reach of the operator. Theworm 253 engages a worm gear 266 fixed on a transverse shaft 26l whichis journaled between a plate 262 and the frame member 21a. A reel 263(Figure 4) is fixed to the shaft 261 and has a flexible cable 264attached thereto, the other end of the cable being fastened to the chainand link connection 123a. When the handle 256 is turned, the reel 263winds up the cable 264, exerting a downward pull on the caster wheelstandard and thereby raising the main frame 10a. The lead of the worm253 is such that the worm is irreversible, hence it is unnecessary toprovide detent means for holding the adjusting device in the selectedposition.

The forward, or right hand caster wheel 14a is yieldingly urgeddownwardly by means comprising a spring 265 which is anchored to abracket 266 on the frame member 220. and is attached to one end of achain 210. The other end of the chain 210 is trained over and is fixedto a cam pulley 21! (Figure 5) mounted on a transversely disposed shaft212 which is journaled on the rear end of the frame member 220.. A roundpulley 213 is fixed to the shaft 212 alongside the cam pulley 21l, and asecond chain 214 is fixed to and trained around the same, the chain 214being fastened to the cap a at the upper end of the standard 25a. Thecam pulley 21l is so shaped and so positioned on the shaft 212 that thepull exerted by the spring 265 on thestandard 25a is substantiallyuniform throughout the range of movement of the standard. This isaccomplished by varying the distance from the shaft 212 to tneline ofpull of the chain 210 so that when the spring 265 is stretched beyondnormal, as when the standard 25a is suddenly thrust upwardly by passageof the caster wheel over a hill, the increased tension in the spring iscompensated for by a shorter moment arm, and the transmitted forceremains practically the same.

It is believed that the advantageous features of our improved sidedelivery rake will be readil apparent to those skilled in the art fromthe above, description, and what we claim and desire to secure byLetters Patent'is:
